Social criticism examines literature in the cultural, economic, and political context in which it is written or received. Keeping this definition in mind, it is necessary to understand the political, cultural and economic environment in which Lennon the above famous words. â€Å"Imagine† was released in 1970. The late 60’s was the time of the Vietnam War and also the time when the peace movement was at its peak. Anti-war demonstrations were a common sight on every street corner. Anti-communist sentiments were at an all time high following the war. The countless lives lost by both sides made plenty realize the fruitlessness of war and prompted them to spread the message of love, unity and peace. Due to ubiquitous demonstrations all over the world, there was social unrest. Compulsory military service added to the social unrest. Fathers and Sons left to fight the war without much hope of returning back alive thus adding to the civil unrest. As always, any period of social unrest has an adverse affect on the economy. Due to the huge war expenses and lack of man power to run the economy, the late 60’s and early 70’s experienced an economic downturn in the United States which was felt throughout the world. By the end of the 60’s, The Beatles had acquired a worldwide fan base and legendary iconic status among the youth of the world. John Lennon, the most prolific and famous of the Beatles, wasn’t averse to making political statements through his music. He knew that he had the power t...

The Art Of Preaching Old Testament Narrative - 791 Words

Robinson enlightened me on the importance of going back to re-read also study the Old Testament. However, through further study, I glean there is a hermeneutical side also a homiletical side that will help me improve my sermons bristle with accuracy, clarity, interest, also relevance. Preaching an Old Testament narrative is challenging due to the fact of misreading them (Scriptures), read them poorly, or read them to prove a point outside the purpose of the biblical storyteller. This is called abuse of the Bible considering, it leads to what God says is bearing false witness. Therefore, according to the author Mathewson, one struggle with the Old Testament narratives considering there is no patience, also are tempted to press for an enumeration of facts or set of clear and sharply formulated the idea (fluff); to be honest, it is mostly ignorance. Second, o ne finds the Old Testament challenging considering its role is minimized in the canon as faulty. The importance of the Old Testament stories gives instruction to things not repeated in the New Testament, Creation, law, also covenant. Intimidated by the language and literature of the Old Testament is another challenge in preaching the narratives, as well as, one being enslaved to a particular style of exposition (Mathewson 12-25).

ethics in the workplace Essay - 1320 Words

How do Workplace Ethics Apply to the Goals of an Organization and the Work of Employees? Abstract Ethics in the workplace are viewed in the business world as an attempt to communicate its expectations and standards of ethical behavior in the workplace. In recent years, managers and workers have expressed concerns about how ethics in the workplace apply to the goals of an organization and the work of the employees. The Ethics Resource Center (www.ethics.org) assist leaders to impact their organization by identifying ethical risks and establishing systems to emphasize higher standards for business conduct. According to Joshua Joseph (2000), of the Ethics Resource Center, â€Å"in†¦show more content†¦In order to create an ethic program, a manager must determine goals and objectives for the program. Goals are the essential part to any training session and have critical implications. With an ethics program in place, managers can increase productivity and improve morale by establishing an ethical culture within the organization. To establish an effective program a manager must do the following: †¢ Establish a code of conduct that reduces risk of criminal behavior †¢ Detect wrongdoing, foster quick investigations, minimize consequences †¢ Demonstrate company’s ethical/legal philosophy during an investigation †¢ Reduce fines if company is found guilty of wrongdoing †¢ Enhance company reputation and stature Importance of Ethics in the Workplace In todays society, ethics plays an important role in the workplace. Ethics is vital to creating the company culture of an organization. An organization uses ethics to decide how it wants to do business and how its reputation is viewed from an outsiders perspective. Good ethical practices can prevent these things from happening. While at work there are certain guidelines that should be followed to make sure that everyone feels comfortable.

Observations Carried out on Children Should Be Objective

All observations that are carried out on children should be ‘objective’. According to the Oxford online dictionary objective means that a person or their judgement should not be influenced by personal feelings or opinions in considering and representing facts – in other words, the observations should be unbiased. You should always be non-judgemental about the child and base your observation from only what you have seen on that specific day, not taking any past events into consideration – it is important that all children are treated fairly and equally to make the observation valid (based on the truth – Collins English dictionary) it is essential to make observations valid to increase objectivity. The opposite of objective is subjective.†¦show more content†¦In some pictures some people may even notice things in the pictures that other people do not – this shows that everyone has a different perception. Another thing to consider when observing children are the ethical issues. Every setting will have ethical protocols which are a set of standards that practitioners need to abide by. The observation of children must be undertaken ethically and in line with any protocols that your college or education establishment abide by. The behaviour of a practitioner in a childcare setting should conform to the standards and expectations of their college – whether or not they are observing children, they are required to act as a role model to young children so it is essential to behave appropriately and conform to all protocols both in college and in placement. There is a chance that the group of children may be a potentially vulnerable group, therefore practitioners need to act in a child’s best interest at times. There are many ethical considerations that you will be required to take into account when carrying out observations on children. The first of these would be permission. To carry out an observation it is vital to gain permission and approval from the child’s parents, the supervisor and possibly the head of the setting – this is for safeguarding reasons, some parents may feel uncomfortable having their child observed so they could deny permission, which parents areShow MoreRelatedTDA 3.71675 Words   |  7 Pagesprogression made by all the children in their class and be able to report back to parents and other members of staff.

A Pyrometer Is A Non Contacting Device Free Essays

A pyrometer is a non-contacting device that intercepts and steps thermal of a radiation, a procedure known as pyrometer. Its a device that can be used to find the temperature of an objects surface. It has an optical system and a sensor. We will write a custom essay sample on A Pyrometer Is A Non Contacting Device or any similar topic only for you Order Now The optical system can concentrate thermic radiation onto the sensor. The end product signal of the sensor is related to the thermic radiation or irradiance j* of the mark object through the Stefan-Boltzmann getaway, the invariable of proportionality ? , called the Stefan-Boltzmann invariable and the emissivity ? of the object j^ { star } = varepsilonsigma T^ { 4 } This end product of the pyrometer is to used to deduce object ‘s temperature. There is no demand for direct contact the between pyrometer and the object, as there is with thermocouples and opposition sensors ( RTDs ) . hypertext transfer protocol: //www.instrumentationtoday.com/wp-content/uploads/2011/08/Radiation-Pyrometer.jpg Radiation pyrometer The radiation pyrometer is the organic structure or the fluid is emitted of the temperature is to be measured and besides to focused on a thermic receiving surface, it is normally in the froth of a really thin strip of blackened Pt besides the alterations in temperature of this surface is measured. Therefore in a radiation thermopile a big figure of thermocouple in the signifier of strip are connected in the series and besides arranger side by side so that all the non junction which are blackened to increase the energy, when it absorbing ability the pyrometer besides fall within a really little mark country. The thermoelectric features of the thermopile are really stable because the thermocouple are seldom connected straight to the furnace and besides non present at a temperature of more than a few hundred grades. The thermopile has more advantage over other sensors, and besides give the same response to incoming radiation in the scope of 0.3-20Â µm irrespective of wavelength within the scope. The standardization of a entire radiation pyrometer is done with black organic structure radiation. For illustration the end product temperature T4 since the pyrometer is use to mensurate the temperature of a fluid or a hot organic structure, the emanation is non right known, so the temperature that measured will non be corrected and some grade of mistake will be present. The mistake are calculated and some grade of mistake will be present. The mistake are calculated as the end product thermometer temperature is straight relative to T4. E = K?„T4 The ‘K ‘ is a changeless by distinguishing we will acquire: DT/T = d?„/4?„ 10 % of the mistake in the value of emanation will ensue in 2.5 % mistake in the temperature of the radiant object that is measured Pyrometric cone hypertext transfer protocol: //upload.wikimedia.org/wikipedia/en/1/17/Figure_6.gif It ‘s the device that seldom used to estimate heat work during the fire of ceramic stuffs. The cones, frequently used in sets three as shown in the illustration, are positioned in a kiln with the wares to be fired and supply a ocular indicant of when the wares have reached a needed province of adulthood, a combination of clip and temperature. Therefore, pyrometric cones give a temperature equivalent and besides are non simple temperature-measuring devices. Resistance thermometer File: Rtdconstruction.gif Resistance thermometer besides called opposition temperature sensor ( RTDs ) are detectors used to measured temperature by collating the opposition of the RTD component with temperature. Most RTD element consist of a length of mulct coiled wire wrapped around made from a pure stuff, Pt, Ni or Cu. The stuff has a predictable alteration in opposition as the temperature alterations.

The diagnosing is in a ( clinical ) Electrocardiogram with up to 12 leads. Key block lead devices are the electrode addition amplifier, high-pass filter ( normally 0.5 Hz ) , low-pass filter ( around 150 Hz ) and right-led thrust circuit. Each electrode required a preciseness instrumentality A to pull out a really little signal that rides on a 300 millivolt to 700 millivolts common-mode electromotive force. Typically, this amplifier will utilize a higher supply electromotive force to enable a high addition without inveighing the amplifier in the presence of the common-mode electromotive force from the organic structure. This A can be a distinct instrumentality amplifier or an incorporate instrumentality amplifier. Second and 3rd phase active-filter amplifiers are needed to put a really specific set ( 0.5 Hz – 150 Hz ) to capture the EKG wave signal. Basically these will be low noise, 5V amplifier with good appropriate bandwidth. In add-on, low-noise, low-power amplifier are needed for the right-leg-drive feedback map. In multi-channel from system, it normally is a 12-lead ECG proctor will be utilizing for a common users, it is to multiplex signal into a common ADC system. The cardinal typical demands for the multiplexer ( mux ) are low on-resistance and low charge injection on the system. By and large a specific mux is selected to fit the electromotive force demands of the filter amplifier and the ADC. It is besides common for multichannel ECGs to hold automated lead sensing to enable multi-configuration operations. Generally, a low on-resistance switch is used in this circuit every bit good Multiplexers like the ISL43681 and ISL43640 series are first-class picks for medical devices as they can run a scope from 2V to 12V. In add-on, they have low-on opposition of 39 to 60 ? , which lower deformation and reduces ‘kick-back ‘ electromotive force from the system. Their low charge injection of 0.3 personal computer ( picocoulombs ) reduces error part on charge-redistribution on a ACDs system. For 3-lead portable ECG application, low-power instrumentality As from a CMOS procedure may be a better choice on the multiplexers. Since CMOS inputs of course provide a high-impedance input, the demand for external is eliminated, salvaging cost. A good pick for the input amplifier can present active feedback with a really precise base line compensation electromotive force, low 1/f noise, highly low beginning, and low impetus versus temperature. What ( electrically ) is being measured? It is electrical activity of the bosom musculus as it changes with clip, normally printed on paper for easier analysis. Like other musculuss, cardiac musculus contracts in response to electrical depolarization of the musculus cells. It is the amount of this electrical activity, when amplified and recorded for merely a few seconds that we know as an ECG. How is the electrical signal gaining control? A signal-averaged EKG is a more elaborate type of ECG. During this process, multiple ECG tracings are obtained over a period of about 20 proceedingss measuring several hundred cardiac rhythms to observe elusive abnormalcies that increase hazard for cardiac arrhythmias. These elusive abnormalcies are normally non detected on a field ECG. A computing machine captures all the electrically signal from the bosom and averages them to supply the physician item sing how the bosom ‘s electrical conductivity system is working and shown on the ECG system. It show a radio detection and ranging on the system, it ‘s a heart-beat frequence rate. hypertext transfer protocol: //www.maximintegrated.com/images/appnotes/4693/4693Fig02.gif Complete circuit of a functional block diagram ( ECG ) QUESTION5 Voltage to frequency From the BASIC of electromotive force to frequency the LM231/LM331 convertors ideally suited for in simple low cost circuit from parallel to digital transition, the preciseness frequence to voltage transition, long-run integrating, additive frequence transition or demodulation, and many other map. The end product when used a electromotive force to frequency convertor is a pulse train at a frequence exactly relative to the applied input electromotive force. The transition of electromotive force to frequency it provides all the built-in advantages of the electromotive force to frequency convertor techniques, and easy to use in all standard electromotive force to frequency converter application. Further, the LM231A/LM331A series attained a new high degree of truth versus temperature which could be attained with expensive electromotive force to frequence faculties. The LM231/331 are ideally suited for usage in digital system at low power supply electromotive forces and can supply low-pri ced parallel to digital transition convertor can be easy channeled through a simple exposure isolator to supply isolation against common degrees The LM231/LM331 use a new temperature-compensated band-gap mention circuit, to supply first-class truth over the full operating temperature scope, at power supplies every bit low as 4.0V. the preciseness timer circuit has low prejudice currents without degrading the speedy response necessary for 100kHz voltage-to-frequency transition. And the end product are driving 3 TTL tonss, or a high electromotive force end product to 40V, yet is short-circuit against Vcc. Frequency to voltage The LM 2907/LM 2917 series are frequency to voltage convertor with a high addition op A or comparator designed to run a relay, lamp, or other burden when the input of frequence reached are exceeds a selected rate. Most of the tachometer uses a charge pump technique and offer frequence duplicating for low rippling and full input protection in two versions ( LM2907-8, LM2917-8 ) or end product swing to land for a nothing frequence input. The op A or comparator is to the full compatible and the tachometer has a drifting transistor as its end product from the frequence. This characteristic allows either a land or supply referred load up to 50mA. The aggregator may be taken supra Vcc up to a maximal VCE of 28V. The indistinguishable basic constellations include an 8-pin device with a below referenced tachometer input and its internal connexion between the tachometer end product and the op amp non-inverting input. This version is good suited for individual velocity, either dual velocity or frequence shift or to the full buffered frequence to voltage transition application. The more frequence is configure and supply a differential tachometer input and uncommitted op A inputs. With this version the tachometer input may be floated and the op amp become suited for active filter conditioning of the tachometer end product. Question 6 Differential force per unit area flow measuring is dependable with the assistance of microprocessor engineering discharge coefficient can be stored on the instrument and measurement temperature absolute force per unit area allows to rectify unstable parametric quantity such as denseness and speed to obtain the mass flow rate. This are called multivariable mass flow metres. The beginning of differential force per unit area flow measuring is the Bernoulli equation represent energy preservation for a fluid component Orifice home base Orifice home bases are most normally used for uninterrupted measuring of fluid in pipes. They are besides used in some little river system to mensurate flow rate at locations where the river passes through a culvert or drain. Merely a little figure of rivers are appropriate for the usage of the engineering since the home base must stay wholly immersed i.e. the attack pipe must be full, and the river must be well free of dust. In the natural environment, big opening home bases are used to command forth flow in flood alleviation dikes. In these construction a low dike is placed across a river and in normal operation the H2O flows through the opening home base unimpeded as the opening is well big than the normal flow cross subdivision. However in inundation, the flow rate rises and inundations out the opening home base which can so merely base on balls flow determined the physical dimension of the opening. Flow so held back behind the low dike in a impermanent reservoir which is easy discharged through the opening when the inundation subsides Venture The Bernoulli rule and its corollary, the venture consequence, are indispensable to aerodynamic every bit good as hydrodynamic design construct. Airflow and hydrofoil designs to raise and maneuver air and H2O vass ( aeroplanes, ships and pigboats ) are derived from application of the Bernoulli rule and the venture consequence, as are the instruments that measure rate of motion through the air or H2O ( velocity index ) . Stability indicant and control mechanisms such as gyroscopic attitude indexs and fuel metering devices, such as carburettors, map as a consequence of gas fluid force per unit area derived functions that create suction as demonstrated and mensurable by gas/fluid force per unit area and speed equation from the Bernoulli rule and the venture consequence. Nozzle A nozzle us a device to command the way or features of a fluid flow ( particularly to increase speed ) as it exist ( or enters ) an enclosed chamber or pipe via an opening. A nose is frequently a pipe tubing of changing transverse sectional country, and it can be used to direct or modify the flow of a fluid ( liquid or gas ) . Nozzles are often used to command the rate flow, velocity, way, mass, form, or the force per unit area of the watercourse that emerges from them Pilot tubing The basic pilot tubing consists of a tubing indicating straight into the fluid. As this tubing contain fluid, a force per unit area can be measured, the traveling fluid is brought to rest ( stagnates ) as there is no mercantile establishment to let flow to go on. This force per unit area is the stagnancy force per unit area of the fluid, besides known as the entire force per unit area or ( peculiarly in air power ) the pilot force per unit area How to cite A Pyrometer Is A Non Contacting Device, Essay examples

Pros and cons of technology free essay sample

Pros mean advantage and cons means disadvantage. Any coin have two side same way technology have some advantages and some disadvantages. The pros and cons of technology are numerous. By technology we can use more things like internet, computer, telephone etc. According to me technology has more advantage than disadvantage. Technology: The systematic application of scientific knowledge to a recent product, process, or service. Pros: Technology has made a great impact on many separate such as the society as a whole. The positive ways that it affects society are many such as that it has brought luxury to life, increases access to knowledge, provides a communication stage and has generally made life easier. The arguments against its benefits are many. Once, human life use to be limited because no technological applications were available. Routine life then involved a lot of physical activity but now in these times, people have more luxury and in the process have neglected the need for activity and exercise. For the pros of technology, the use of advanced technologies like robotics and artificial cleverness has proved helpful in life-risking tasks like mining and space exploration. The Internet has brought an important positive change to the entertainment and promoting industry. Advertisements can reach the masses within seconds over the Internet. The entertainment media has move forwards only because of the advancements in technology. Mobile phones have broadened the horizons of communication by enabling suitable long-distance Positive Effects of Technology: The positive effects of technology are that things can occur faster in the world. Transactions can happen immediately over the Internet. News travels around the world about events from the furthest corners. People can band together for a cause worldwide†¦ One benefit of technology is that people are able to access information and each other much faster and easier than ever before. One advantage of technology is that people are cess your test results and medical charts quickly due to technology in the medical profession. With technology, companies save money because they do not have to pay travel cost or even have to have a physical location. Technology makes life convenient and efficient. Technology as a Teaching help Just a decade ago, teachers used chalk boards, then progressed to white boards and now they are using smart boards. Smart boards are advanced boards which allow teachers to teach and share information and knowledge with students in a multiplicity of ways. Computers audio-visual ability from PowerPoint presentations and other animation software are used to present information in an interactive way which invites greater interest from the students. Moreover, use of projectors, screens and addressing systems (speakers and microphones) allow teachers to teach a large number of students simultaneously. Studies show that these teaching helps increase concentration levels of students and have led to improvements in student class attendance. Easier convenience of Information With internet being a vast information base, students are finding it an effective tool for obtaining knowledge. Students can now retrieve all types of information easier and faster than ever before by way of their personal computers or cell phones. The Internet has given education a new dimension – distance learning and online teaching. Students no longer have to physically attend classes to be a part of one classroom. They can attend a class virtually at the comfort of their home. Numerous educational institutes are currently offering online courses, where students interrelate with their teachers over the internet and access learning materials from the institutions’ website. Advantages of Educational Technology Computers and related technology are essential to the learning process in several ways. Although some people feel that the use of technology can have a negative crash on the socialization and development of critical thinking skills of young children and teenage, and may be misused by some instructors, they are fundamental and significant tools used in classrooms and the workforce, and foster greater understanding of different cultures. In his article, The Computer Delusion (1997), Oppenheimer reports that the number of jobs requiring computer skills increased by 12% from 1983 to 1993  and the pay for jobs involving computer skills showed an average increase of between 10 to 15 percent. He also notes that the Clinton administration pledged to move public education into the twenty-first century by ensuring that computers become as common in classroom as blackboards. With estimated costs to accomplish this improvement between 40 and 100 billion dollars, Oppenheimer further stated a state task force, which lobbied the California legislature to spend 11 billion dollars for computers in schools over the next few years. Technology has revolutionized how teachers teach and how students learn. The importance and benefits of education technology to the teachers and students cannot be ignored. Technology has made it easier for teachers to impart knowledge to the students and for students to acquire it. The use of technology in schools has also made the process of learning and teaching enjoyable. Cons: There are also several cons to technology. Unfortunately, some forms of technology could cause a person to become dependent on that technology and unable to function well without access to it. For example, many people have problems driving without a GPS to guide their route. Other cons might include the constant need to upgrade the technology, lack of patience and constant need for instant gratification, a decline in writing skills, or even a lack of physical interactivity. It has made people lazy, overexposure can lead to internet addiction and it has made man overly dependent on it. These impacts have much changed the lives of individuals as well. It has sprouted many unethical practices such as hacking, computer espionage, addiction and lack of regulation. It has also deprived man of the warmth of contact. Communication lost its personal touch. People have also become overly dependent on machined and technology to do their work for them. They rely on machines than human intellect. Machine replacing human beings may cause great issues such as unemployment and crime. With the developments in technology, we may be able to enjoy all the pricey luxuries but miss out on the little priceless joys of life.
